EMC approved (89/336/EEC).

The PD 3940 is a communication module, providing an interface from the P-NET fieldbus to
RS232 devices, such as printers, card-readers, barcode readers and other equipment not having built-in fieldbus facilities for P-NET. This enables such devices to be integrated into a P-NET fieldbus system. It can be used in conjunction with the varied collection of distributed P-NET input/output and control modules, which provide digital, analog, flow and weighing facilities.

Application examples:
Printer interface, for printout of tickets, alarms and reports.
Card-reader interface, for entrance control.
Bar-code reader interface, for production control to track the flow of materials.
